So I'm having a rather pain in the ass issue maybe you all can help me trouble shoot before I bring it in Friday to my dad's diesel mechanic.
Since I've owned the cruiser, every once in a while when I start it up it will run extremely rough, stall if I rev it up and barely hold an idle. After a few minutes or a couple restarts it will run perfect....then I won't have an issue for a couple weeks....then I might have the issue two mornings in a row, then no issue for a while. John (gofast) figured I wasn't glowing it long enough and wasn't firing on all cylinders. I started glowing longer (5-10 second after light goes out) and only had the issue once. I changed the fuel filter thinking it may be clogging up.
The truck has been running great for a week, then today it started the roughest it has yet. I let it sputter and tried to choke it a bit and it died about three times when I would let up on the throttle (very low rpms). Finally after trying applying gas pedal gradually (it would hold higher rpm) when I would let off the pedal it would stall right away...did that a couple more times then wouldn't even start...it would turn over but just stall as soon as it was running. Finally, I tried one last time, turned the ignition while lightly pushing on the pedal and it sprung to life, rpms were normal and idled smooth...I drove it to class today (30min drive) with not one issue and it started up perfectly once my course was done.
My limited knowledge is telling me it is a diesel issue and not a warming up issue (or maybe both?). It seems like it isn't getting diesel and sputters (like when I changed out the fuel filter) or like there is air is in the line, then it finally clears itself out. I'm trying to figure out if it is possible air in the line, injectors aren't getting proper diesel, primer pump is on its way out, or if fuel pump is on its way out. I have driven it for a week with no issues since the fuel filter was replaced.
As I wrote before it has developed a slight diesel leak, which I'm having looked at Friday, that slows down once the truck has heated up. I have had sputtering issues before the leak.
Any suggestions for when I meet up with the mechanic Friday would be greatly appreciated. He is a younger guy who is very good for working on diesel trucks...He has seen my cruiser once, thought it was very cool and excited to have a look at it and help out
edit...and from what I've read/researched..it isn't puffing any white smoke.
